I am working on deregulate scenarios. We have a 100% tax exempted Contract account that has supplier contract and Budget billing as well. We are trying to create an installment plan for supplier contract and it generate an BB adjustment document . This BB document has Portion tax (SCTAX in DFKKOP) . When we try to estimate the revenue distribution we are facing issue in Revenue distribution as system subtract tax amount . So, we can distribute exact amount to supplier .
Could you please help to identify the tax amount and get rid of it .
