Unable to initialize delta for 2LIS_02_HDR

Hi all,

Need Help !!!

We came across an issue while initializing the delta for 2LIS_02_HDR in SAP BW 7.4.

All the 3 options are in grey color. Due to this we are unable to do delta update as well.

Reinstalled from BI content, replicated again in BW, recreated Infopackage, all this failed as the options are still in grey color only.

Even the time between ECC and BW were synchronized recently.

For your reference, please find the screenshot:
