Hi Gordon!
From the right I have UDF for choosing the spare parts of auto. I want to add a spare part, for example to item master data (OITM). I enter every field step by step 1 - 4 by choosing frome use tables linked in every field. I choose fielf 1 (Brand) for example TOYOTA and in the use table of 2(Model) field i see only values that belong to TOYOTA that to say corolla, carina, vista and so on. But to find any component exactly i put on the loupe in the field 5 and see a table where all types of auto parts in the world but they are filtered with parametrs in 1-4 fields. I chhose needed component and get in the 5 field any code of a choosed part. Then i d liked to link the table of filed 5 to field Description too and to filter component with code in field 5 in order to get item description from the use table. I used the one method of filtering in all fields Here i see that i can to filter values using use fields but I don't use it in standart field description, although the usual selection of elements of any use table works. As a result a see that the problem that doesn't work the selection and filtration in the field description but it works in in UDF.
