You can set max value base on "ExportApplicationQuantity" value dynamically

"text" [min]="0.001" [max]="sBill.ExportApplicationQuantity" class="form-control" maxlength="12" required name="SBQuantity-{{in}}" #SBQuantity="ngModel"
id="SBQuantity" [(ngModel)]="losses.SBQuantity">
"SBQuantity.errors && SBQuantity.touched && SBQuantity?.errors.required" class="alert alert-danger">
SBQuantity is required.
"SBQuantity.errors?.max">Must be in range
