I have created a custom field for sales master data.
The need is to check if the input field is correct (correspond to a value of the table)
It seem's it can be done with the custom Validate Customer Badi. But it's not allowed to do a select on the table ZZ1_F19F..... I've tried to add a class in Custom Reusable Elements but I can't access directly to the table ZZ1_F19F.... neither if I create a CDS for this table
Do you have any idea for this requirement ?
