@AkshaySandhu i have performed the same task it is throwing an error Cannot create an L-value from the given expression with property ‘set_Item’ because the target object is null in UiPath.
You are missing this part at start just below the Build Data Table activity
In this you should be assigning variable str_ExtractPath, the path of Extract folder.
@AkshaySandhu i have assigned that in arguments
check value of it at run time, possibly check all used variables. None of variables in used should be null.
Str_extract value
@AkshaySandhu maybe there are only CAMS,NDML,CVLKRA,KARVY and not other folder’s like DOTEX and BSE.
