Button "New Row" in "Enter delivery times" on SUS does not work

Hi all.

We have ECC-SUS scenario with SRM server 7.1 and ECC 6.4

Bycustomizing theSWETYPVtransaction,we sendthepurchaseorderscreated inECCtoSUS.

At thisPOinSUSwe willgeneratethePurchase OrderResponse,however, whenwe want tocreate new records in"Enterdeliverytimes"usingthebutton"NewRow", the system non activates thecapturefields.

In fact, thebuttondoes not do anyprocess and not shown any error in SLG1 or ST22 transactions.

We need tomake theserecordsofdeliveries foreach position of thePO Response.

Please, any suggestions?

kind regards.
