Limitation Of UIpath ? Throwing an error while merging the data table used with Document Understanding

[Rahul_Karn]

Hello Everyone,

I have a question regarding the error which i am getting while extracting the information from inovices using document understanding. When it extracts the information from item table it throws an error while merging the data table for items .

So the scenario is the columns of the item table in different invoices have a different alignment or sequence than those defined in the taxonomy.

In the taxonomy I have defined the columns for item table in the order PRODUCT DESCRIPTION , QTY, UNIT_PRICE , AMOUNT
but in one of the document i am extracting the UNIT_PRICE before the QTY as it is in the
structure of that invoice . and in result i get the error Merge Data Table: Cannot find table 2.

So, Is this the limitation of UiPath ?Can anyone help me how to proceed in this scenario ?

Hi!

Are you merging the tables in a UiPath process?
What activity are you using?

Hi Sven, Yes I am merging table in a UiPath process. Its a workflow using document understanding to extract the information/data from invoices and storing them in database .It works fine for the columns having similar orientation in the invoices as defined in the Taxonomy . But it throws error when the columns for item table has different orientation. Please find the attached screenshot where it throws an error.

Great!

Althought it looks like you’re simply out of index.
datasetResult.Table(2) doesn’t seem to exist.

I get the same error message when i try to merge a new but empty dataset with an existing datatable.
