3790426 - Down Payment in Purchase Contract - Supported Item Categories

When creating a Purchase Contract with the Item Category = Service (Product Type Group 02), the Down Payment in Purchase Contract flag is displayed but remains disabled/greyed out and cannot be selected, preventing contract-based down payment processing before a release order is created.

 The behaviour differs depending on the item category used on the contract line item:

• When a contract item is created with Item Category: Material (Product Type Group: Material / 01), the Down Payment fields (DP Category, Down Payment in Purchase Contract (Flag), Down Payment Amount/Percentage, Down Payment Date) are available and can be maintained.
• When a contract item is created with Item Category: Service (Product Type Group: Service / 02), the Down Payment fields (DP Category, Down Payment Percentage, Down Payment Date) are available and can be maintained,whereas the Down Payment in Purchase Contract (Flag) functionality is greyed out / disabled and cannot be maintained.
