There are several reasons that can cause this.
The most common is the UPN. The UPN is a required field, without this, although the child will exist on Weduc itself, we cannot generate a payments account for them.
The first thing to check is whether there is a UPN for this parents child's in your MIS system. If there is not, first add one. You will then need to wait overnight for the UPN to import into Weduc.
On the next day, first click your name in the top right and then the school name the main drop down.
Then select Users/Mailboxes on the left.
Now select Student to expand the area.
Find the student in question, then select Actions next to them.
On the drop down that appears, select Create/Update Payment Account.
The child will then appear on Weduc Payments and the globe/icon will appear for the parent instantly.
Note: The child will not appear in their groups immediately. You will need to wait for the next overnight sync for this.
