Master Data Services 2019 - Derived Hierarchy issue

Question

Hello,
I've been facing an issue with a Master Data Services (MDS) derived hierarchies. At first the hierarchy worked fine but after some time (do not know how long) I am not able to load the MDS data via Excel with MDS 2019 Add-in. I am receiving an error "Exception from HRESULT: 0x800A03EC". If an attribute which is filtered by the derived hierarchy is excluded from the load, the data is loaded just fine.
I believe that that the issue will not be related to MDS since it's working fine via Web Application. Moreover, two of my colleagues does not have this issue.

Results from tracing:
MDS Warning and Error tracing on the server:

Excel Add-in MDS log:
Attached in txt file.

App versions:
Microsoft SQL Server 2019 MDS Add-in for Excel 15.0.2000.5
Microsoft® Excel® for Microsoft 365 MSO (Version 2110 Build 16.0.14527.20234) 64-bit
MDS database located on Microsoft SQL Server 2016 (SP2-CU17) (KB5001092) - 13.0.5888.11 (X64) Enterprise - Server A
MDS 2019 service - Server B

I also tried to reinstall the whole Office 365 and MDS Add-in for Excel but the issue still persists. I've also compare app versions with my colleagues and the versions are the same. I would be grateful for your opinion and potential solution.

Thank you,
Petr

Hi @Stodůlka Petr ，

The error code 0x800A03EC (or -2146827284) means NAME_NOT_FOUND; in other words, you've asked for something, and Excel can't find it. In general, you are asking for something with a specific name and it doesn't exist.

If the field value starts with an equal sign (=), it can sometimes cause an exception.

You can first exclude the data you need to import

Hi @YufeiShao-msft ,

Thank you for your answer. Well I am not able to exclude the data since they are important to users. My only solution is to turn off the derived hierarchy but it's not the solution what I want since the derived hierarchy works fine for some of my colleagues.

Since I only use MDS Add-in for Excel and do not use any manual functions start with (=), I think that Excel is not able to find some function/object of the MDS Add-in.
I also tried to disable the error checking for formulas: Options-->Formulas with no success. Based on the link you sent, It also could be related to a language. However, my OS and Excel use English. So this shouldn't be a problem.

I really do not know where could be the source of this issue.

Thank you,
Petr
