Process order Screen Exit

[former_member605955]

I added two Custom fields to the COR1,2,3 screen, but I can not save them to the table.

Here's what I did:

1. Add two Z fields to CAUFVD and AUFK as Append structure

2. Create a new project in CMOD

3. Add Enhancement PPCO0001 and PPCO0020

4. Double-click SAPLCOKO and add Z field in screen painter

5. Double-click EXIT_SAPLCOKO_005 to add ZXCO1U21 coding

MOVE-CORRESPONDING I_CAUFVD TO CAUFVD.

6. Double-click EXIT_SAPLCOKO_006 to add ZXCO1U17 coding

TABLES: CAUFVD.

MOVE-CORRESPONDING CAUFVD TO E_COCI_AUFK.

7. After saving, activate it

I can see added fields in the screen COR2 but doesn't save data without error message

Checked table but no data.

Debugging confirms that the data is well beyond the parameter E_COCI_AUFK. But I can not save it.

If you know where the problem is, please answer it. Thank you.
