Tables for historical changes of PM Task Lists

[m_karimi]

hi there

can anyone help me to find out when and who removed the operation from task list? there is an MP which has a task list attached; however the task list operation has been removed, therefore the MP which was supposed to be called on July 22nd, 2024 is on hold. 

I added new operation on 08AUG2024 as shown in screenshot#1 and SAP generated new node and counter in table PLPO, can anyone tell me how I can find missing node 1 ?!

screenshot#1

then operation 20 has been deleted (as created in error) which updated deletion indicator in table PLAS in screenshot#2.

any thought, solution?!

hi @Vaibhav-Mishra 

unfortunately this didn't help! table CDHDR shows the date the task list created and dates that my colleague and I updated the task list as shown below!

still remains as mystery!

FYI, we upgraded the system in Feb 2024 from S4/hana 2019 to 2022; do you think that historical changes in master data don't transfer?! this is the stupid question to ask but came to my mind/

kind reagrds,

Mary

Did you check CDPOS table also? I created a Task list in my system, saved it. Afterwards, I deleted one operation. I can see entries in CDHDR and CDPOS table. I can see the operation number also. You may take help from an ABAP programmer. In ABAP there are FMs which can help you to readthe exact change in TL. You can check with FM => CHANGEDOCUMENT_READ_HEADERS and CHANGEDOCUMENT_READ_POSITIONS
