Bug in new PowerQuery 2.22.4007.242 when used together with PowerPivot (was fine on v. 2.21): EmbeddedMashup changes with every save RRS feed

  • General discussion

  • Hi,

    I have an issue with this latest update, when working together with PowerPivot.

    Here’s my setup: Excel 2010 64bits + PowerQuery_2.22.4007.242 x64 + PowerPivot for Excel SP2 x64

    When trying to refresh an existing excel that has PowerPivot use a PQ data source (via the Existing Connections menu item), I get a refresh error. I have been able to pin down the error to the following:

    Every time I **SAVE** (not before saving) the workbook, the EmbeddedMashup connection sting of PQ changes (with PQ 2.22). This did not happen with PQ 2.21. With this happening, the PowerQuery refresh breaks.


    BEFORE: Working: Excel with PowerQuery 2.21

    Workbook PowerQuery Connection:
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(7bd72702-510c-4616-a072-c970477e94c8)$;Location=Query1; (…. rest of string does not change )

    PowerPivot data connection:
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(7bd72702-510c-4616-a072-c970477e94c8)$;Location=Query1; (…. rest of string identical )

    The two “$EmbeddedMashup” strings were identical, and saving the Workbook did not affect them. Nothing strange.


    Workbook PowerQuery Connection: (does not change at all)
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(7bd72702-510c-4616-a072-c970477e94c8)$;Location=Query1; (…. does not change )

    PowerPivot data connection:

    Before saving: Original (PowerPivot refreshes work)…
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(7bd72702-510c-4616-a072-c970477e94c8)$;Location=Query1;

    After 1 save: (PowerPivot refresh does NOT WORK anymore): EMBEDDESMASHUP CHANGES!
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(5bafbf30-bfd5-47e0-bdc8-1025438c1992)$;Location=Query1

    After saving again: (PowerPivot refresh does NOT WORK anymore, embeddedmashup changes again)
    Provider=Microsoft.Mashup.OleDb.1;Data Source=$EmbeddedMashup(fd8cb919-e5e5-4f7a-8d59-cc658af29ccd)$;Location=Query1

    … etc

    This breaks compatibility between PowerQuery and PowerPivot. It all worked well with v 2.21. Could you please fix the bug?

    Workarounds I’ve found:
    – Downgrade to v. 2.21
    – Alternatively, copy the whole connection string from PQ to PP. It will make refreshing work, until you save the workbook and it breaks again….

    Thanks for all – and by the way, it is really great that you have included PQ in general O365!

    Best regards

  • I can confirm the same bug for my system. The issue also occurs for Excel 2010 32 bit.

    Strange how hard it is to get the Power Pivot connection right.
