LSMW For T-code ME21N
There is an issue with the LSMW for T-code ME21N. I have completed 11 steps successfully. The 11 steps are as follows:
1. Maintain Object Attributes: - I am using Standard batch/direct input.
2. Maintain Source Structures: - I understand that it can work if I make two source structures on same level (1st for the header & 2nd for the line items).
3. Maintain Source Fields: - I am maintaining all compulsory fields of both structures.
4. Maintain Structure Relations: - In this way, there are two structures
I am mapping MBEPOH with header source structure and MBEPOI with line source structure.
5 Maintain Field mapping and Conversion Rules: - I am mapping all compulsory fields.
6 Maintain Fixed Values, Translations, And User- Defined Routines: - This step is executing successfully. 7 Specify Files: - I m specifying two-text one for header data and 2nd for line items.
8 Assign Files: - Then I assign it to respective structures.
9 Display Read Program: - This step is executing successfully.
10 Read Data: - This step is executing successfully.
11 Display Read Data: - This step is executing successfully. This means mapping is perfect.
12 Generate Conversion Program: - BUT It is giving an error, which I m not able to get the reason of it. The error is this: -
Generation cancelled. Reason: Invalid
I have seen the relations b/w structures are perfect and unable to get the reason why this error is coming.
Would request you all, to help me to correct this error.
