Question asked in both interviews: How do you configure the integration of FI and MM or SD in the background?

1 FI/MM interface configuration FI/MM sets posting accounts for all inventory movements through tcode OBYC. The system uses different TransactionKeys to determine different movement types/business types. For the meaning of these TKs, There is a more detailed explanation in SAPLIB, please refer to it. The configuration of accounts can be done at the ValuationArea (Plant) and ValuationClass layers as needed. In particular, I think the most interesting thing in FI/MM AccountDetermination is the account definition of TK for GBB. There is something called GeneralModificationKey. This GMK is directly connected to MovementType; in addition to many standard GMKs, users can also customize , and associate them with the custom MovementType to determine whether different MTs are connected to different posting accounts. 2 FI/SD interface configuration FI/SD sets the posting account for billing through tcode VKOA. Users can create their own account definition data table. The account is at the COA level and is posted to the FI and CO vouchers respectively through the two condition types of KOFI/KOFK. Since PricingProc. is associated with SalesOrg., the account must first reach the SalesOrg. level in the Organization. The subsequent AccountKey is associated with different PriceConditionTypes in PricingProc., which determines the final sales revenue, discounts, and additional Expenses, accruals, etc. are divided into different accounts.
