Explanation
You can use the valuation grouping code to group together plants assigned to company codes with the same chart of accounts. This reduces the effort to configure account determination because you only need to maintain one set of valuation classes and account assignments for each valuation grouping code instead of each plant.

Explanation
When using split valuation for your refurbishing process to differentiate between materials based on the condition of the material, you must consider that for each possible valuation type, the price control must be moving average price (MAP). This means that each valuation type has its own moving average price that is updated after each goods receipt or invoice receipt. You cannot use standard price for split valuation because it would not reflect the different values of the materials with different conditions.

Explanation
The Purchase Requisition Touch Rate card in the Procurement Overview app shows the percentage of all purchase requisition items that require manual intervention during processing. A high touch rate indicates that there are many exceptions or errors that prevent the automatic conversion of purchase requisitions into purchase orders. You can use this card to analyze the reasons for manual intervention and take actions to improve the process efficiency.

Explanation
The quota base quantity is the total quantity of a material that is to be procured over a certain period of time from various sources of supply. The quota arrangement specifies how this quantity is to be distributed among the sources of supply. If a new supplier is added to an existing quota arrangement, the quota base quantity must be updated to reflect the new situation. This way, the new supplier will be considered as if they had been part of the quota arrangement from the beginning. The other options do not ensure this, as they only affect the existing sources of supply or the source list.References: [SAP Help Portal], [SAP Community]
