Tax code is not updated in BSEG but it is showing in BSET for certain documents
I noticed that for some documents, the tax code is not showing in bseg table but it is showing in the bset table. This has cause the data to be inconsistent between the two tables.
This is odd because in this case when I display the document in FB03, the tax code field is empty in the line item but there is value for tax code when I display the tax data for the same document.
Is this some kind of system bug or is this normal? I've search for OSS note but don't seem to be able to find it.
