I have a Qlikview document to show Requisitions, PO's and then the Accounts Payables. I'm missing some joins from the PO to AP as I do not get the relating AP information for a PO. I have added my document. Please can someone advise.
After checking your file, I think the issue is in the links 'Join to AP invoices D' and 'Join to PO dists I' in your APInvDists table. They show subset ratios of 0.01% and 0.05% respectively. (so basically no fit) As there is no fit, you won't see a link in your data either. This could mean that your 2 fields you're linking each time are not similar. I'd start by checking those.
I'd first have a look at the different variables that make up your link.
e.g. AP_Invoice_Distributions_All.PO_DISTRIBUTION_ID vs PO_Line_Locations_All.LINE_LOCATION_ID
Put theze next to each other, and compare them. Best would be to do this for a PO/AP that should be common.
This is what you defined to be the link between AP & PO, but there seems to be a very limited fit. This may be due to a format difference, even though the data are similar. In that case, you re-format one of the variables so that they match, and the link becomes much stronger. This is similar for the other link I mentioned.
