How to disable ODATA return limit of 25 entries

[pa2t]

Hi All,

How would I disable the limit of 25 entries for ODATA REST endpoints for windchill?

ex. <server>/Windchill/servlet/odata/v3/DocMgmt/Documents ---- only returns 25 entries

Thanks,

Patrick

@pa2t  I am not sure what you mean by "disable ODATA return limit of 25 entries".

Assuming what you want is increasing the limit of entities return, try below:

Specify header

Prefer : odata.maxpagesize=<no of entities up to 200>

For example: adding below the header will increase the entities return count from 25 to 150

Prefer : odata.maxpagesize=150

Currently, the maximum root entities retrievable is 200.

Hi.

@amarsingh , is there a way to configure this on the OData connector itself (that is on TWX side)?

Thanks!

I know a way by adding a custom header. There is an post already about Thingworx swagger connector but the same should be applicable for Thingworx OData Connector.

FYI, there is also a Windchill knowledge article that touches on this:

Yes, this is the original article that explains that REST request headers should be modified to include the parameter:

"Prefer" + "odata.maxpagesize=100"

But it does not explain how to perform that at OData connector level.

I have created a short document on this here https://community.ptc.com/t5/ThingWorx-Developers/Adding-a-Custom-header-in-Thingworx-Connector/td-p/647507. Let me know if you still face difficulties

Thank you very much @amarsingh !

I will test that soon, but I'm pretty sure it's the best solution, especially to automate the parameter for route services (the ones created just by using API maps).
