Analytics API: Dimensions cannot be specified more than once

Support - Assistance technique

Hi Devs

We’re working on a report that accepts multiple (indicator) dx parameter values. From this list we’re trying to build an API call that includes numerator + denominator formula UIDs so that we also display numerator and denominator totals in the report. Example parameter for 3 indicator UIDs:

dx=A9s6E9l4W8z;Bt5H0q5L3h7;eo2N8j1S9k4

For each of these indicators we look up the associated data elements UIDs that make up the num + denom formulas. The *new API call looks like this:

dx:Cl4D9i5T6j2;N2m4W6w3N4r;cx6F4m5U5v2.JO2HBbjqU3c;Cb3X7x9P7b2.JO2HBbjqU3c;Cb3X7x9P7b2;cx6F4m5U5v2;K2j3J8b4H6c;J1a6I8c1G2k;A9s6E9l4W8z;Bt5H0q5L3h7;eo2N8j1S9k4;cq3K6v5R5e3;Dv1K3w4Z3u0;cl2E3i6X5z9

Executing the API calls result in the following error: Dimensions cannot be specified more than once.

From this list it’s obvious to tell which UIDs are repeated but how do we work around it? Do we run multiple/separate analyic API calls for those numerators/denominator that reference category combinations from those that don’t?

Regards,

Greg

Hi Greg,

can you post the entire request analytics URL ?

Which version are you on?

If 2.20 the api response should tell you which dimensions are duplicated.

regards,

Lars

Hi Lars

Problem solved!

It runs successfully under version 2.20 while v2.19 returns error message Dimensions cannot be specified more than once: [[de, type: DATAELEMENT, items: [[cx6F4m5U5v2, type: null, items: , legend set: null, filter: null], [Cb3X7x9P7b2, type: null, items: , legend set: null, filter: null]], legend set: null, filter: null]]

Original call:

api/analytics.json?dimension=pe:LAST_12_MONTHS&dimension=dx:Cl4D9i5T6j2;N2m4W6w3N4r;cx6F4m5U5v2.JO2HBbjqU3c;Cb3X7x9P7b2.JO2HBbjqU3c;Cb3X7x9P7b2;cx6F4m5U5v2;K2j3J8b4H6c;J1a6I8c1G2k;A9s6E9l4W8z;Bt5H0q5L3h7;eo2N8j1S9k4;N2m4W6w3N4r;Dv1K3w4Z3u0;cl2E3i6X5z9&dimension=ou:LEVEL-3;JLA7wl59oN3&hierarchyMeta=true&displayProperty=NAME&showHierarchy=true
