Mass closure purchase contracts

Hi community,

we have a list of purchase contract transactions (>150) that have to be closed.

We checked and there are not standard solution to do this update via Mass Update or CSV upload.

Thus, we create this following script:

var k = [6426656, 6426762, 6403895, 6404031, 6404033, 6404034, 6404035];
for (var j = 0; j < k.length; j++) {
    close_remaining(k[j], 'purchcon');
}

We are running this script via console and it is working. However, it's working ONLY in the browser transaction page; it means I cannot run this script for multiple transactions.

Do you have a solution for this issue?

Thanks

Riccardo
