In Acumatica, it is possible to define dynamic attributes that one can link to records such as business accounts, customers, vendors, stock items etc.
(Explaining them is out of scope of this article - see Acumatica help for details)
The screens below show an example attribute of "Company size" (assume it is linked to the "Business Account" records in the system):
Once properly configured, you can include the respective attribute value in to a Generic Inquiry result set in Acumatica:
These will now be included in your GI() calls to that inquiry in Velixo:
There is a peculiarity of Acumatica that you need to be aware of to properly filter by attribute values.
On the screenshot above, note that the GI() call returns a Description value of the attribute ("1-100").
However, for the purposes of OData filtering, you need to specify the values from the Value ID column instead! ("100").
