Process Gap in ML81N: – Generally in standard SAP system, we have to maintain the same “Tax Code” with same properties in Purchase Order & Service Entry Sheet Acceptance. So we don’t need to change the Tax Code at the time of Service Entry Sheet Acceptance just because that already maintained in Purchase order.
Now in our existing SAP system we can make changes in the “Tax Code” at the time of Service Entry Sheet Acceptance instead of existing Tax Code, which is not traceable & improper entry in SAP.
To reduce this we have to make the following configuration changes in SAP System.
To make Tax Code in Display Mode we have to set Tax Code Field as non-editable mode in Item Condition at Service Entry Sheet Acceptance (ML81N).
Assign the Tax Code Field in “Define Screen Layout for Service Entry Sheet in Display mode.
Path- SPRO>IMG>material Management>External Services Management>Define Screen Layout.
Double Click on Entry number “5”.
Change the entry from Tax Code as Opt. entry to Tax Code as Display.
Confirm your entries and click n Save Button.
After Making these changes you are not able to make changes in tax condition at the time of Service Entry Sheet Acceptance (ML81N).
