I am looking for a way to find out how tables are associated in business logic. The Dicionary and SE11 was my first start. And I read the article How to find Relations between tables in SAP and a few similar documents. But something seems to be wrong either in the dictionary or in my brain. ;-)
One example of what I mean is the relation between LIPS and VBAP.
- When you try the SQVI trick explained in the article linked above, you see links from LIPS-VBELN to VBAP-VBELN and LIPS-POSNR to VBAP-POSNR. But if you would create a query based on this links, it would fail (see below).
- If you explore LIPS in SE11, you find VBUK and VBUP as Checktables for VBELN and POSNR. But this leads to nowhere.
Obviously, the business logic is a bit different. The real link from LIKP to VBAP is
- LIPS-VGBEL must match VBAP-VBELN, and
- LIPS-VGPOS must match VBAP-POSNR.
So, what I am trying to find is a way to explore this business logic. How are tables linked? Is this information present at any place in the Dictionary?
Thank you very much in advance,
best regards
