Hi Team ,

I am stuck in a part of requirement where all 

week _no.	jan 2023	feb 2023	......	dec 2023
1	552
2	670
.
12	990
.	990
52	990

the value from the current week should be repeated thru all the future weeks . I am stuck at two points .

1. future weeks are not coming so i used master calendar but didnot satisfy my requirement.

2.  The data is not coming as every week we have specific materials and they are not getting mapped .

Please help me out of this .
