Question

Hi,

We have one document library and list in SharePoint.

Each time when a file gets uploaded in document library its metadata are stored in column of SharePoint library
We need to extract that metadata and compare that with masterList, if the metadata field value is not present in masterlist then it gets added in the list else it is not added.

First step : When a file is aded or modified in document library

Second : used http to get all the details present in master list

Third: used parse json for http of master list

fourth: used http for document library to get details of files in doc library

fifth : Parse JSON for doc lib

sixth : used compose action to get metadata field value

adding condition to check whether the metadata field is present in master list or not

but the problem here is
compose action is taken from document library where only 2 files are uploaded.

but in condition when we trying to compare the metadata present in masterlist or not, it is taking 24loops, but there is not 24 files present

Pls help to solve this
