Appending query error

[Anonymous]

I have 2 tables:

Monthly:

Date                PERNR     Region

12/31/2018         1               X

and Daily:

 Date                      PERNR      Region

1/17/2019                  1                  X

I am appending these 2 tables so that the Daily Table looks like:

Date                     PERNR         Region

1/17/2018                1                 X

12/31/2018              1                 X

But when I load this table to the front end, it throws the following error

I dont understand why this is causing a problem as I have similar projects in the same pattern (That is multiple PERNR Records and same type of relation between the tables) but it has not thrown this error. Any suggestions?

Thanks!

Hi @Anonymous

Does that make sense? If so, kindly mark the answer as a solution to close the case.

Hi @Anonymous

Looks like your daily table is at the "One" end of One to Many relationship in your model. So, when you append rows to the daily table , which makes the joining column duplicated values, which means the relation is no more "Many to One", hence the existing relationship fails. This append makes the relationship as Many to Many , which needs to be elminated by introducing a relationship/ bridge table.

Hi,

But as i said, Ihave other reports with the exact relationships. And I have another table that looks exactly similar:

Ex: Monthly load in Dec has:

PERNR    JOB             Date

1               X                12-31-2018

Then, during jan this employee is still present in the company and the table then looks as foloows:

PERNR    JOB             Date

1               X                12-31-2018

2               X                 1-31-2018

But this does not give me such an error

Hi @Anonymous

How abt the data in the other end table? Does it has duplicate for PERNR '1'? Many to Many is supported , it should be solved .

Either you can provide the full sample set of records for both the tables involved in the join or you can upload sample PBI file for further help on this.

Thanks
