Add Custom Field to Purchase Requisition – MEREQ001
I looked for a detailed document about ME51N-ME52N-ME53N add custom field in SCN but i have not found fully described. That’s why i decided create this blog.
Symptom :
Some customers need to add custom fields for their purchasing request documents then try to copy this field other subsequent purchasing documents such a purchase order. You can benefit from this blog for these requirements.

I suggest that please read MEREQ001 enhancement document ! Because, SAP inform you how to design your developments step by step.
When you finish explainations of SAP , you will get information about this user-exit.
Sum up ;
1- Append your custom field to CI_EBANDB .
2- Create subscreen and add custom field to screen number 111.
3- EXIT_SAPLMEREQ_001 is used to Export Data to Customer Subscreen for
Purchase Requisition(PBO).
4- EXIT_SAPLMEREQ_003 is used to Import Data from Customer Subscreen for
Purchase Requisition.
5- If you get DUMP like a –> Runtime error : DBSQL_SQL_ERROR , Exception : CX_SY_OPEN_SQL_DB., go to SE14 for EBEV then ‘Adjust and activate’ !
I created a project for implementation in CMOD named ZMM and MEREQ001 is added such a component. Then you can work on it.
SOLUTION :
1- Add ZZUSER to CI_EBANDB .
2- Create subscreen and fill out modules.

Layout :

ABAP Codes :
PBO –> Status module.

RESULTS :
Purchase Requisition
EBAN is updated correctly !
I hope that you will need to copy custom fields to subsequent documents such a purchase order. You have to add same field to subsequent purchasing document and fill out fields in subscreen referance to purchase requisition.
If you want to copy PR custom field to PO custom field with a referance, you can benefit from PBO of customer screen in SAPMM06E 0111 CUSTSCR1 SAPLXM06 0111 ! (Screen exit PO)
Enhancement IMP –> MM06E005 Customer fields in purchasing document .
Read custom field PR .

Dear Mehmet Ozgur Unal ,
Nice document, As some of the only consultant have ABAP knowledge with functional module, Otherwise Functional will never have any idea about ABAP normally. You are blessed with both. So that's why document cover functional and technical aspect as well.

Excellent blog Mehmet Ozgur Unal.
My scenario is little different.
First of all I replaced the field with a pushbutton and modified relevant code.
Now upon testing I found out that PBO and PAi of Screen 0111 is only called when the Customer Data tab is active. Usually, an end users will not click that tab, and when he clicks on Check or Save button, standard SAP code is called instead of Screen 0111 modules.
So, how can we ensure this that Screen 0111 PBO and PAi is called irrespective of Customer Data tab being active or not.
Hi Mehmet,
First very thanks for this blog.
Can you please share the screen shot of ME51N where this Custom Fields would be displayed ?
Thanks,
Sijin
Hi Sijin,
You can find screen belongs to Pr in the blog.
please check again

Links to the SAP notes could be useful:
very good
why Module status_0111 output not work ?
i create new include and write codes ( by Break point) but not work ?
I found my error.
Even that in CMOD all components showed activated. I had to go to SE38 and activate it there.
Nice Document God Bless You!!!!
Dear Mehmet,

Hi!
Firstly thanks for the post 🙂
The issue that i have now is the custom fields must be filled at Header level...Is there any way to create this custom fields at header level?
Regards!
Hi Mehmet Ozgur Unal,
I hope you're doing well. I have a few questions, hope you can answer. I need to add a new column in ME51N, so I add a new field in MEREQ3211GRID structure, exactly in CI_EBANDB, correct? Always I have to add new fields in CI_EBANDB? I added the new field here but I don´t see this new field when I select "Change Layout" in alv options. I need to create this field in screen 0111 to see it in the ALV layout?
I need to create a validation, in MEREQ001 the validation apply in screen 0111 or in ALV performance?
Thanks in advance
