Hi, 
 I have a scenario for the closed requests when i am reopening whatever the documents that i have attached in old closed case after reopening new case for correction all the old case documents needs to displayed under new case other attachments tab so the documents is displaying correctly 
 But now in those documents whatever the document type is "MMRF" i want that document needs to be removed and it should not display under other attachments tab after reopening case could you please suggest on this how to achieve tried using remove or delete document of that specific type but didn't worked 
 Below is the pv variable data that i am passing to reopened case: 
 pv!checkRequest_cdt.attachments.documentId saving it in other attachments pv variable target 
 attachments is one column which is nested CDT in checkRequest cdt 
 The data in cdt will be like below in that below if documentType = MMRF that one i dont want to be displayed under other attachment for reopening case 
 attachments=[attachmentId=58917, requestId=27808, fileType=xlsx, documentTypeIndex=, documentType=Request File, documentId=315155, DocLink=0902e],[attachmentId=58918, requestId=27808, fileType=pdf, documentTypeIndex=, documentType=Other Request Attachment, documentId=315156, midasDocLink=0902e71f86ef340f],[attachmentId=58919, requestId=27808, fileType=pdf, documentTypeIndex=, documentType=MMRF , documentId=315161, DocLink=0902e],

Hello dharanik2600 To r emove the MMRF type document from the pv! variable you can follow below steps:- Iterate through the pv!checkRequest_cdt.attachments list using a for loop. Inside the loop, for each attachment, check if the documentType equals "MMRF". If the document type is "MMRF", create a new temporary list (filteredAttachments). Add all attachments except the MMRF one to this list. After the loop finishes, assign the filteredAttachments list back to the pv!checkRequest_cdt.attachments. Also you try using filter function https://docs.appian.com/suite/help/24.1/fnc_looping_filter.html Let me know if that works for you.
