Summary

Imagine your project in cutover phase. You need to make changes to a large volume of master or transaction data.

For Example,

      1.     Delete all the line items in multiple purchase requisition (PR)

2.     Or close all the line items in a PR

3.     Or Un-fix all the line items in a PR

Even though we have options of using BAPI/BDC and this can be done programmatically, such approach would require additional development and testing efforts.

How about using a standard SAP transaction to achieve this functionality?

This document describes the usage of standard SAP transaction MASS for mass change in master/transaction data. We will consider example of updating purchase requisition details using mass transaction. We conclude with a discussion on when it would not be recommended to use MASS transaction.

Prerequisites

1. Knowledge of master and transaction data concept in SAP

2. Knowledge of navigating and working on SAP transactions

3. Knowledge of basic ABAP and Business Objects would be advantageous for customized development under MASS framework

4. Knowledge of various terms in SAP modules like MM or SD is desirable to understand example presented in this document

5. In mass maintenance, many objects can be changed at the same time. For this reason, the mass maintenance tool must be used only by experienced persons.

Overview of MASS Maintenance Tool

Mass maintenance is a generic (cross-application) tool that can be used for the following Purposes:

To change large quantities of data

Here, there are the following differences for the individual maintenance of objects in a Specific application:

·   The user selects the field to be changed from a list.

·   The consistency checks occur collectively when saving the changes and not simply when entering or changing a value.

·   Changes can be made simultaneously to several objects.

Mass maintenance is therefore particularly useful if you have to adapt existing data stocks to a changed situation.

Example: A purchasing group is taken over by another, and in a particular plant, you have to assign all materials that were assigned to the old purchasing group, to the new purchasing group.

To create new data

In some situations it is not possible to change existing values, but to create new data instead (such as if you want to determine an additional unit of measure for a material).

Sample Scenario: Updating Purchase Requisition

Scenario Description:

Consider the below requirements that is to be accomplished as part of cutover activities.

1. Delete all the line items in multiple purchase requisition (PR)

2. Or close all the line items in a PR

3. Or Un-fix all the line items in a PR

We need to update below fields to attain the desired results as per the requirement.

Table Name	Field Name	Field Description	Usage
EBAN	LOEKZ	Deletion Indicator in Purchasing Document	To delete the PO / PR order or Item.
EBAN	EBAKZ	Purchase Requisition Closed	To close any line item of the PR
EBAN	FIXKZ	Purchase Requisition is Fixed	To update the line item as Fixed line item.

Run Transaction MASS.

We need to know BO type for Purchase Requisition. If you do not know the BO number, use transaction SWO3 to search for appropriate BO from Business Object Repository.

In present case, BO number is 2105.

Press F8 to run transaction.

As shown above, system displays an information message notifying about update of multiple tables at the same time.

Accept the information and proceed. We see only one table is listed for this BO.

Tables that can be updated using MASS for given object are maintained in table MASSTAB. This table can be maintained using SM30 transaction.

In our case, we need not alter standard SAP customizing.

Now select table EBAN and press fields tab.

We see fields allowed for mass maintenance in the following screen.

We do not see the fields that are needed for current requirements listed in screen above. We can maintain the fields required for mass maintenance in table MASSFLDLST.

Go to SM30 transaction.

Maintain field’s data in MASSFLDLST table.

Save the changes we have made.

Now go back to MASS and repeat the entire procedure till selection of fields and press F8. We may find they even though some fields are maintained in step above, we do not see them in selection criteria list.

In such cases, check table MASSAPPEX to see which Function Module is used for limit fields and limit ‘selection of fields’ activity.

‘Limit selection fields’ restrict some fields to be removed from selection criteria and ‘limit fields’ allows certain fields to be removed from maintenance. We can attach our custom FM copied using existing SAP FM to further restrict some fields or remove restriction from some fields.

If everything is OK till this stage, we can press F8 in MASS and accept warning.

Next screen allows us to restrict our selection.

Select the Purchase Requisition number which is needed to modify.

This will display all the data maintained in the standard table ‘EBAN’.

Select all the required fields which we need to change here.

Update all the data fields which we need to update in the table and save the data.

Status of the operation will be shown after that as messages from update task. This log provides us with the details of errors occurred in any.

Expected Outcome:

For the above example of change on line items of a Purchase Requisition ‘0010000000, below data is updated in table EBAN.

All the Updated data is also shown in ME53N transaction:

In the above screen shot, item number 3 and 5 are fixed and the item 4 is set for deletion in purchase requisition.

Useful Customizing:

In table MASSFUNC we can maintain FM which is used for updating the data using MASS maintenance. This is useful if you need to create similar functionality for your custom business object.

For this first you need to create an entry in table MASSNAME for your custom BO.

Instead of maintaining each of above customizing table individually; you may use transaction MASSOBJ to complete all customizing. You would be able to find out application exit points and tables listed in this transaction. 🙂

Frequently Asked Questions:

1.    Are there any customized variants for MASS transaction?

1. Some customized transactions (variation of MASS tool only) are provided by SAP for specific objects.
2. Below is list of some of these transactions.
