Network error when using Patch function: Length must be between 0 and 100

(1) ShareShare
ReportReport
Posted on by SumoTechSimon 78

Whist trying a simple patch function in Apps I am getting this error. I am using a checkbox and the code for OnCheck is as follows:

Patch(DespatchLines_1, Defaults(DespatchLines_1), {Despatch_RMA:ThisItem.RMAAutoNo, Despatch_PN:ThisItem.Product, Despatch_PO:ThisItem.'PO#', Despatch_Serial:ThisItem.'Serial #',Despatch_Desc:ThisItem.'Product Description' ,DespatchL_RDN:Header.LastSubmit.Despatch_No})

 

The strange thing is that I am using an almost identical function in another app and that works fine.

 

Looking forward to your help.

    Hello SumoTech,

    The problem is that one of the fields within the Patch function has a maximum limit of 100 characters, and it seems that during field compilation, you have exceeded this limit.

    Could you please try again, ensuring that each field has a maximum of 10 characters?

    Just for test purpuse.

    Best Regards,
    Federico

    Hi Simon,
     
    I get the same error sometimes when moving data from SharePoint lists into Dataverse tables.

    I have found that adding the following function to set a variable immediately after the patch statement sometimes can show me the column which caused the issue, but it doesn't seem to be 100% reliable and sometimes shows nothing.
     
    Concat(Errors(Bookings), Char(13) & Message & " (" & Column & ") " & Error)
     
    It can be useful in pointing you in the right direction, especially if you have lots of columns in the Patch statement. 
     
    If this doesn't work I usually end up building two collections and checking the length of every column of incoming data which could be the cause.
     
    Good luck!
