Hi a-ovbord,
Thanks for your prompt response.
Please find the details of this issue below.
- Create two document libraries named 'Library A' & 'Library B' in a SharePoint site.

- Create a flow to copy new and modified documents from 'Library A' to 'Library B' as described below.

- Create a new document 'Arpan-1.docx' in 'Library A'
- Edit the document 'Arpan-1.docx' in 'Library A' and wait to be copied the changes in 'Library B' automatically.
- Fetch the data of 'Library-B' using SharePoint SOAP API
- Repeat the steps #4 & #5 and notice that sometimes Etag attribute is not being changed in API response. Kindly see some API responses for your reference below.
Response-1
"rs:data" = {
ItemCount = 1;
text = "\n ";
"z:row" = {
Etag = "{D36938FD-B529-469D-8353-5A99621AEDE8},16";
"ows_AccessPolicy" = "100;#0";
"ows_Author" = "7;#Roland Reddekop,#i:0#.f|membership|roland@megafile.ca,#roland@megafile.ca,#roland@megafile.ca,#Roland Reddekop";
"ows_BSN" = "100;#4292";
"ows_BaseName" = "Arpan-1";
...
Response-2
"rs:data" = {
ItemCount = 1;
text = "\n ";
"z:row" = {
Etag = "{D36938FD-B529-469D-8353-5A99621AEDE8},1";
"ows_AccessPolicy" = "100;#0";
"ows_Author" = "7;#Roland Reddekop,#i:0#.f|membership|roland@megafile.ca,#roland@megafile.ca,#roland@megafile.ca,#Roland Reddekop";
"ows_BSN" = "100;#222";
"ows_BaseName" = "Arpan-1";
...
Response-3
"rs:data" = {
ItemCount = 1;
text = "\n ";
"z:row" = {
Etag = "{D36938FD-B529-469D-8353-5A99621AEDE8},1";
"ows_AccessPolicy" = "100;#0";
"ows_Author" = "7;#Roland Reddekop,#i:0#.f|membership|roland@megafile.ca,#roland@megafile.ca,#roland@megafile.ca,#Roland Reddekop";
"ows_BSN" = "100;#222";
"ows_BaseName" = "Arpan-1";
...
Note- In the above case, I have updated the document 'Arpan-1' three times. Last two response contains the same Etag value. Ideally, the Etag value should be changed every time after step #4.
Please suggest on this issue.
