Error: iXBRL warning for shares less than 1p in Accounts Production Advanced

Scenario

Solution 1: when iXBRL warning is shown in the Allotted, called up and fully paid shares section of the report

Make sure you are signed in to Accounts Production Advanced as Administrator.
Right-click on the narrative of the report that generates the error, and select
Go To XML
Go to line 99 of the XML code, which will be similar to the following example.
report.CurrencySymbol
<data>
 <inline xbrl-concept="core:ParValueShare" xbrl-period="CurrentPeriod" xbrl-scaling="0">
 <data condition="value!=System.Math.Truncate(value)" currency-format="#,0.00">value</data>
report.CurrencySymbol
<data>
 <inline xbrl-concept="core:ParValueShare" xbrl-period="PriorPeriod" xbrl-scaling="0">
 <data condition="valuePY!=System.Math.Truncate(valuePY)" currency-format="#,0.00">valuePY</data>
Go to 'currency-format' in the line of XML that refers to the CurrentPeriod, then enter the amount of
#
s that is equivalent to the share value.
note
For example, if the share value is 0.0001, then you need to enter: 
currency-format="#,0.#####"
. If it is 0.00001, then you need to enter:
currency-format="#,0.######"
.
Repeat step 4 for the line of XML that refers to the PriorPeriod.
note
If you've more than one share class with different nominal values, both will be shown in the report correctly.
