Hi Experts,
My Client has implemented SAP POSDM. In the current design, we bring taxes at the header level. So if a transaction has both sales and returns, the tax is apportioned among sales and returns line items.
In ECC tax is always positive and is positive for sales and negative for returns. Hence postings are incorrect.
When a transaction containing a sale and return is processed, the tax is apportioned between the two line items. A real example is a transaction below
Sale = +189.99$
Return = -99.99
Tax = +12.06
When the transaction is processed and aggregated,
WPUUMS is generated as
Sale +189.99 Tax 7.91
Return -99.99 Tax -4.15
So this is the problem where the net tax posted is 3.76 and not 12.06. POSDM is apportioning the tax among the line items because Tax is sent at Header and not line item level.
Thanks
