IWO10018: User Fields in Maintenance Order
One of the very frequently asked questions in this space, is about the subject matter, i.e., How can I add Custom fields to my Maintenance Order? In the recent months the author had replied 3 times to discussions related to this topic. It is thought that this topic if documented would be helping many.
This documentation is intended to enable the readers to create the Custom fields in the Maintenance Order, update the Order Master data Table and also display these fields in IW38 Order list output.
Create Custom fields in the Order Table
The table of our context is AUFK. We need to append our Z-fields to this through the include structure namely CI_AUFK.
The process of creating any custom field starts with creating a Data Element with desired Type and Length or with desired Domain name and with the Field Labels we want to have for the Customer fields. For our Demo, we have created Two Data Elements, namely :
1. ZCUSTFLD1 (Domain CHAR12 and Field Label ‘Customer Field 1’)
2. ZCUSTFLD2 (Domain CHAR40 and Field Label ‘Customer Field 2’)
Now let us create our Customer fields Run Tcode SE11 –> give value AUFK in the Database Table field –>Click on Display. Scroll-down to find include table CI_AUFK. Double click on this, Go to Change mode and Add 2 new fields of our interest as shown in the picture and Activate.
As seen in the picture, we have created Two Customer-Fields namely ZZCUSTFLD1 and ZZCUSTFLD2. It is essential for all Customer fields used in Enhancement purposes to be prefixed with ZZ. Activate the Structure.
Enhancement and Screen-Exit
1, Create an Enhancement Project say ZPMORDER using Tcode CMOD.
2. Assign Enhancement IWO0018 to this project.
3. Click on Components in the picture above to reach this screen.
4. Activate by clicking on the Activate Icon (shown in picture above)
As we see here, there is One screen-exit (screen 0900) and Two Function-Exits namely EXIT_SAPLCOIH_018 and EXIT_SAPLCOIH_019 in this enhancement. Double Click on this screen number to create a Sub-Screen for holding our Custom Fields. You’ll get this pop-up. Press Enter and Continue.
You’re in the screen below, where you’ll give a Description, Select the Subscreen Radio button, Save and Activate.
Click on Layout Arrow in the Application Toolbar of (See the picture above) to reach the Screen-Painter pop-up window, where we will be creating :
1. A Box to hold our Z-fields
2. Text Fields to for Z-field labels
3. Input Fields for Z-fields
The input fields should be referred to the Dictionary fields we have just created. (AUFK-ZZCUSTFLD1 and AUFK-ZZCUSTFLD2)
See the picture.
1. Declare table AUFK
Declare table AUFK in the top include LXWOCTOP of Function group XWOC by Clicking on and creating the include ZXWOCTOP .
2. Codes to be given in Function-Exits
Go to the following screen of the User-exit
Double click on the Function-Exit EXIT_SAPLCOIH_018 and put the following code in the include ZXWOCU15.
MOVE-CORRESPONDING COCI_AUFK_IMP TO AUFK.
Similarly put the following code in the include ZXWOCU16 of the Function-Exit EXIT_SAPLCOIH_019.
MOVE-CORRESPONDING AUFK TO COCI_AUFK_EXP.
Now let’s see the effect of work done so far.
Create a Maintenance Order (IW31). You will see an Additional Tab named Enhancement has been added here by the system, in which our Custom fields appear with their labels and the input fields.
Now let’s add some values in these fields and Save the Order.
Run IW32, open the Order and verify whether the values are updated to table or not. If they are appearing in the Enhancement tab as you have entered and saved, this means the AUFK table has been updated with these values when Order was saved.
Let’s have these Custom fields in the Order list output namely the ALV of Tcode IW38
So far we have succeeded in creating our Custom fields and updating the values to the Order Master data. Next natural requirement of a user would be to have these fields in IW38 ALV screen. For this purpose we, need to create an Append Structure in the Structure RIHAUFK_LIST, as shown in the picture below. The
Tcode is SE11 again for this task. Here we have created an Append Structure named ZCUSTFLD and in this structure we have added both the Custom fields.
Now let’s create one more Order, fill the custom fields with some values and Save. The second order is to have ALV output in IW38. (Because single Order in the output takes to IW33 screen instead of ALV screen). Now run IW38 with selection parameters to display these 2 orders we created. Click on the icon shown , You’d find the Custom fields in the Column-set list, Bring them to Displayed list on the Right hand side.
Now if you go to IW33, unlike all other greyed-out fields, the Custom fields in Enhancement Tab will be seen Editable. Though there is no provision to Save the edits here, you’d definitely like to have these fields too in Greyed-out mode.
For this we need to write a small code in the PBO (Process Before Output) module of the screen 0900 we have created. Double click on the Screen number 0900 of the enhancement,
Now you are in the Flow Logic Tab ,
Un-comment line MODULE STATUS_900. and D’Click on the STATUS_0900 of the PBO module. Insert the following code between the MODULE, END MODULE lines like this.
MODULE STATUS_0900 OUTPUT.
IF SY-TCODE = ‘IW33’.
LOOP AT SCREEN.
SCREEN-INPUT = ‘0’.
Lastly Do not Forget to
Activate the Function Group XWOC from Tcode SE80. Right click on the Function Group and click on the Activate option
…… and thus we reach to the end of this knowledge sharing Documentation.
1. As this is largely a Technical job, it is recommended to be developed through an experienced ABAPer, especially Part1 which involves Activating the Standard table AUFK.
2. The Environment of Author is ECC 6.0 with no EHPs, hence the document applicability.
Expecting this document too would be of use to many of the members,
