Entry Aids for Text Items in Purchasing Document

When creating purchasing document, the relevant G/L account is automatically determined by plant, movement type and the valuation class that derived from the material master data. However, when a text item (without material master data) is input, how can system know which valuation class to use?

There is a "Entry Aids" setting in configuration which will help system determine the valuation class. This entry can be found in IMG -> Material Management -> Purchasing -> Material Master. As shown below:

And configuration is like this:

Each material group is assigned a valuation class and purchasing value key.

At the time of data entry, if you enter a stock material, the valuation class will be copied from the material master data - accounting view.

If a text item is entered, then the valuation class and purchasing value key will be copied from the mentioned configuration.
