Writing Validations in Project System

Writing Validations in SAP Project System

This document will help to understand how to write validations for Projects / WBS Elements.

In few cases the requirement would be to restrict certain things based on some other parameters while creating projects in SAP PS. To achieve this, SAP has provided option to write our own validations. In this document we can see sample case with example end to end. 



1.       Case: Validate Project Definition with Project Profile

1.1     Creating Validation

1.2     Creating step

1.2.1  Defining Prerequisite

1.2.2  Check

1.2.3  Message

2.       Defining Messages

3.      Assigning Project Validation to Project profile

4.      Testing the validation


1.     Case: Validate Project Definition with Project Profile

First 4 characters of project definitions should be common for all the projects which were created using project profile ‘XXXX’

In this case the requirement is whenever we are using project profile ‘HMCL001’ the first 4 characters of project definition should starts with HMCL.

Follow the path:

SPRO >> Project System >> Structures >> Operative Structures >> Work Breakdown Structure (WBS) >> Maintain Validations (OPSI)/wp-content/uploads/2013/11/1_323558.jpg

After execution, select the ‘Project Definition’ node and click on Validation icon as shown.

1.1 Creating Validation:


1.2 Creating step:

Click on Step icon to create step for the validation


Enter the description for Step


1.2.1 Defining Prerequisite

Select Prerequisite to define on what parameters system should carry this validation/wp-content/uploads/2013/11/6_323585.jpg

Select the project profile by double clicking on it.


Project profile = select ‘constant’ and enter the required project profile… in this case Project profile is ‘HMCL001’./wp-content/uploads/2013/11/8_323587.jpg/wp-content/uploads/2013/11/9_323594.jpg

1.2.2 Check:

Now we need to define against the above prerequisite what should be the validation.

In this case we want to check the first 4 characters of project definition. /wp-content/uploads/2013/11/10_323595.jpg/wp-content/uploads/2013/11/11_323596.jpg

Click on Constant icon to enter the first 4 characters of project definition./wp-content/uploads/2013/11/12_323605.jpg

1.2.3 Message


You can define the required message using transaction SE91 by entering message class; in this case the message class is ‘/ISDFPS/MISC’ as below.         

2. Defining Massage:


If you want to give additional information to user about the error, remove the ‘Self-explanatory’ check box and click on Long text icon to enter additional information.


Preview of the long text.


3. Assigning Project Validation to Project profile



After entering Validation, need to select ‘Automatic Validation’ check box.

4 Testing the validation

Project Definition as GMENP114 using project profile ‘HMCL001’. In this case, first 4 characters of the project definition were supposed to be HMCL, but we are using wrong combination. So we can expect error here.


While saving the project, system will validate the project definition with project profile and throws the error as below./wp-content/uploads/2013/11/21_323702.jpg

So now system is giving error while saving project, it means the validation is working correctly.
