Implicitly Enhancement Point

Restricting To Update Vendor Number In MIGO for cross company purchase order

Requirement

We had a requirement that ………..

When doing the initial Goods Receipt of a purchased or subcontracted good, the vendor field on the batch master (MCH1-LIFNR) should be populated with the relevant vendor number.

If this batch at a later stage is once more part of a Goods Receipt – by a cross company purchase order, the vendor field should NOT be updated. The initial vendor number should be kept.

Suppose A: Vendor for company ABC and B and C are plant for ABC.

Suppose Plant B of ABC has order one material from A , in that case in MCH1 table , A will be updated as Vendor .

If the same material will be transferred from B to C , as per SAP standard , in MCH1 B will be updated as vendor which is not correct .

Due to that we have implemented the implicit enhancement to restrict the vendor field updation while running 2^nd time MIGO.

For Example: Follow the below screen shots

0000100366 The vendor already exists in the system

The purchase order 4500074509 for the vendor 100366

Performing 1st time Migo (while doing Migo we are putting the Vend

or batch and system automatically selecti

ng the HLU batch)

2nd look at table MCH1

Here No changes in the vendor field

Performing 2^nd time Migo (while doing Migo we are directly putting the HLU batch not the vendor batch)

3rd look at table MCH1

Solution:

For this requirement we tried to find Exit , BADI but we could not find the suitable one for our requirement , so we had to finally opt for Implicit Enhancement .

For this We have to debug the standard transaction MIGO in Update debugging mode to find out the standard program, which has the implicit enhancement point to implement the same.

In Update Debugging mode ,based on table MCH1(because vendor number is updated in this table for our requirement) we found out

Include Program LMBMMF00 , you can find the FORM UPDATE_MCH1 .

Note:

After going to FORM UPDATE_MCH1 , how to find out and create implicit enhancement.

In that screen , go to menu and click show implicit enhancement.

Click on the sun sign symbol , all will be yellow color u find , according your requirement

Go to context menu , create implicit enhancement option will come create it and write your code and activate.
